DOOR-MOUNTING MEANS.

Application filed May 16, 1927. Serial No. 191,878.

' 5 parallel with said frames. The invention further relates to mounting means of the type embodying a track above the door, carriages movable along said track, and hemzontally swingable arms pivoted on ,vertlcal axes to the door and the carriages, the arms, track and carriages serving as supporting means for the door while the latter ,isbeing opened and closed. The track is necessarily spaced outwardly from the plane occupied bythe door when in its closed position and if the above named parts werethen permitted to act as suspending means for the door, the latter would not hang in a strictly J vertical plane with the frame, butits lower end would necessarilyswing outwardly, due to the manner in which the center of gravity would then act.. ,It is one object of my invention however,.to overcome this tendency by the provision of co-acting means on the upper ends of the door and frame for suspending said door independently ofthe arms,

' carriages and track, whensaid (lQOP'lS 1n its closed position, said co-acting means being so, positioned with regardto each other, as to cause the center of gravity; to

insure hanging ofthe door in a strictly vertical plane. f s It is another, object of the invention to provide a generally simplified, yet an ,efli

' cient constructionfor the door hangers, of

such nature as to permit desired vertical ad-,

it 'or later if desired. a 7

With the foregoing in view,- the.i nvention resides in the novel1 subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

justment of the door when initially hanging the door In the drawings above briefly described, 10 denotes a vertical wall having a door opening 11, and 12 denotes a door movable into and out of said opening, theedge wall of said opening forming part of a door frame, whose remainder is constituted by appropriate framing bars 13 secured to the inner side of the wall 10 and positioned to abut the door 12 when the latteris closed.

Suitably mounted in any desired manner upon the wall 10, at the upper end of the doorframe, is a horizontal track 14 which is outwardly spaced from said wall. A suitable number of carriages 15 are sup.- ported by this track, and horizontally swingable arms 16 have pivotal connections at one end with the carriage and at their other ends are similarly connected with the door 12, the pivotal or hinge axes being disposed vertically. lVhen the door 12 is moved laterally into orout of theframe, the

arms 16 swing about their pivots, and as the 1.

door is slid from one position ,to another, its weight is supported by the arms and carriages, upon thetrack 14;;

,WVhen the door stands.closed,,the carriages 15 are necessarily outwardly spacedfrom the plane which said door then occupies. Hence, if the door were then supported by the arms 16 and carriages 15, the center of gravity would be such as to cause the lower end of the door to swing outwardly from the frame.

Hence, I provide co-acting means at the upperends of the door and frame to so shii't'the center of gravity as to cause vertical hanging of the door, said co-acting means then supporting the weight of the door independently of the carriages 15, track 14: and arms 16. In the present showing, a transverse horizontal finger 1 7 is rigidly secured by bolts or the like 18 to the uppermost of the frame members 18, so that its free end projects outwardly. The upper end of the door 12 is provided with a roller 19 whose axis is horizontal, extends in a plane parallel withthe opposite sides of the door, and is preferably located nearer to the inner side of said door than to the outer side thereof. This roller when the door is closed, rests upon the rigid finger 17 and hence-suspends the weight of the door 12 independently of the parts 14, 15 and 16, and by positioning said roller in the manner described, the

center of gravity is such as to cause strictly verticalhangingof the door 12.

Preferably, the roller 19 is mounted in a U-shaped bracket suitably secured in a notch 21 in the upper end of the door 12.

One or more of these rollers and an equivalent number of the fingers 17 may be em- The carriage 15 herein shown, is provided with two rollers, but in so far as certain features of construction are concerned, said carriage might in some'instance'shave' other numbers of rollers or intact only one. This'carriage is provided'with a laterally projecting portion 22having a vertical open;

below said laterally projecting portion and provided with a*vertical bearing 24 aline'd with said opening'23, the other end of the arm-being provided with appropriatemeans 25 for connecting'it to the door 12. A vertical hanger bolt 26 passes through the bear+ ing 24; and the opening 23, the lower end of said bolt being provided with a head'26 [upon which the bearing 24; rests, while the upper end of said bolt is provided with ad- 1 justing nuts 26 which contact with the upper and lower sides of the projecting carriage portion 22. These nuts permit verturn upon it as the arm 16 horizontally swings; i i

occasion may demand, and by then tighten-l ing both of said nuts, the bolt 26 is held against turning, so that the bearing 24 may I11 the form of construction herein disclosed, the projecting carriage portion 22 is formed by a rectangular metal block contacting with the outermost of two horizontally elongated plates 27 28, between whose 'endstrackwheels or rollers 29 are mounted.

Between theintermediate portions of these plates 2728, is, a spacing block 30. A'pair of transverse bolts 31 pass through alined' openings in the blocks 22-30 and the plates 27-528, the openings of the parts 22g27-28 being indicated at 22527 and 28 respec- If desired, suitable trackage; 33 may be 7 provided at the lower end of the door frame to limit the outward movement of said door f and to otherwise assist in guiding. the latter; u Moreover, any desired locking means "may ing23, and one end of the arm 16 is disposed be employed for holdin'gthe door in closed f part of the presentin'vention and henceis' not describedin detail, althoughfitmayibe considered that wherever the number 34 ap-' pears on the drawings, it indicates or parts of said-locking means; i Iclaimz I 7 1.7 In combination, a door; frame, a door of a'sizefto fit therein,' atrack at" the upper 1 position.
